Online suspended sediment measuring instrument

Functional Application

The online suspended sediment measuring instrument is applied to the online monitoring of suspended sediment in rivers, lakes, and reservoirs. It utilizes sediment measuring sensors based on isotope, photoelectric, ultrasonic, and vibration measurement technologies, combined with sediment calculation systems and wireless remote monitoring technologies, to achieve real-time monitoring of suspended sediment concentration. This design primarily selects the photoelectric sediment measuring instrument.

Operating Principle

The online suspended sediment measuring instrument based on the photoelectric method utilizes a combined infrared absorption and scattering light method, employing dual-beam infrared scattering light inverse projection imaging technology, and applies the ISO7027 method to continuously and accurately measure the concentration of suspended matter. According to the ISO7027 infrared scattering light technology, which is not affected by chromaticity, the concentration value of suspended matter can be directly output as sediment content data, enabling real-time online monitoring.

Measurement Principle: Dual-beam infrared scattering light inverse projection imaging technology, equipped with a built-in self-diagnostic function, ensures stable and reliable data, and includes automatic cleaning and slope correction.
